Of course believing in the supernatural is absurd -- what does that

If, for example, ghosts were real, then this would just mean that
current
scientific theories are incomplete or wrong.
That would just mean the terminology isn't very good. It would be more
accurate to
say you do (or don't) believe in ghosts.
That's a good point.
Of course the non-materialist deals with ontological problems. Do entities perceived
under the influence of psychoactive drugs exist in some sense?
At Iridia, there has been a talk and demo of Virtual Reality. I have been very often
disappointed, but this time I have been quite impressed. They have solved the main
problems, and the immersion feeling was quite realist, in all direction where you
looked, without any screen border, and perfect real time synchronization for any type of
the move of your head or eyes.
Does this involve wearing 3D display goggles such as Occulus Rift?

My son has created a video game, "Homesick", of the exploration/puzzle genre, which will
be available for Occulus. I tried out their goggles and the experience is quite realistic
in terms of looking around. In a test at a video game exhibition many people trying them
could not bring themselves to step off a virtual cliff.

In one demo there was a creature, was it real? Those things are relatively real. Like in
personal nocturnal dream, or when reading a novel, and with comp, like with physicalism,
there is a physical reality, which is a priori different from a machine (as it is a sum
of the work of all machine) "acting" below our substitution level. In arithmetic, one
virtual reality is less virtual than all the others, as it has the "correct" comp
bottom. That define a notion of "physically real", and most entities perceived in
inebriated state are very often not physically real. But they might still be images of
important routine operating in the brain of a large class of possible subject, and be
entities living on alternate reality planes, but still there by Turing-Universal + FPI.
Virtual reality might help people for the thought experiences, and many (new)
things.
But in the long run, we have to be careful, as the poor might one day not afford
visiting a non virtual reality. If we don't think a bit, we might end up all in brains
in vats.
